My" invention relates to a heater for the circulating' water within thejacket of automobile and truck engines, an object thereof being toprovide a device of the character described. by means of. which thewater may be kept hot and the enginewarm in frigid'we'ather by'n'ovelmeans and (with respect'to the first andm'ore important embodiment)without the. employment of electrical power.

A further object of my invention is to provide a device of the characterdescribed which can be readily put intooperation' by the driver of theauto or truck from his position in the. cab thereof.

A further object of my'i'nvention' is to provide a circulating" waterheater in the form. of a small, horizontal, water tube boiler to whichis connected, as a unit, a blow torch specially designed for use withthe said boiler and including selfigniting mechanism integral with theblow torch.

A further object of my invention is to provide a device having theforegoing objects which is eminently simple to operate, inexpensive tomanufacture and which cannot readily become out of order.

With the above more important objects in View and such other minorobjects as may appear as the specification proceeds, my inventionconsists essentially in the arrangement and construction of parts all ashereinafter more particularly described, reference being had to theaccompanying drawings, in which-- Figure 1 is a sectional elevation ofmy device in situ.

Figure 2 is an enlarged sectional elevation of my self -ignitingmechanism.

Figure 3 is a section on the line 33 of Figure 2.

Figure 4 is a side elevation of my device as a whole and illustratingthe same as positioned in an automobile.

Figure 5 is a sectional elevation of an alternative, electrically heatedembodiment of my invention.

Figure 6 is a view similar to Figure 4 of the embodiment of my inventionillustrated in Figure 5.

In the drawings like characters of reference indicate correspondingparts in the different figures.

My invention will preferably; though not necessarily', extend uponeither side of the bulkhead l of an automobile 2 or a truck, an aperture3 being formed in the bulkhead for this purpose. It isto be understoodthat my water tube boiler 4 will be positioned upon the engine side 5.of the bulkhead while the blow torch enumerated 6 as. a whole, will bepositioned upon the cab side I: of the. bulkhead convenient to thedriver.

My water. tube boiler 4 comprises the. surrounding jacket 8 and theinner jacket 9 interconnected"v by the passages Ill, although at thispoint, I desire to state. that the. boiler maybe of: any configuration.as to the arrangement of the: tubes therein. However, the foregoingarrangement permits of the. distribution of a flame through. the centertube ii and the annular tube 5% as. I have indicated by' the group ofarrows 43, the spent heat from the flame being, discharged. through.the. exhaust M. The boiler which. I have described. will be connected upto the conventional water jacket oi an associated engine 15 at any twoconvenient points I5! and I5", preferably by means of. flexible hosewhich will. connect with the water intake and discharge nipples l6 andIT respectively.

The boiler is securedto the bulkhead by means of the surrounding flangel8 which encircles the aperture 3, a sleeve portion i9 projectingthrough. the aperture 3. into the cab below and behind. the dashboard 28to this sleeve, my blow torch 61 is connected.

The blow torchv consists of a fuel tank 2.! which may also. be. securedto the bulkhead. as at 22 if. desired, a conventional pump assembly 23being associated with the fuel tank. Positioned above the fuel. tank isa fire nozzle 24 directed towards the. tubes of. the boiler, the jet 25associated with the nozzle, drawing fuel from the tank H by means of thesupply pipe 26.

The fire nozzle is surrounded by the housing 2"! sufficiently providedwith. air holes 23' to feed the flame from the nozzle 24. The housing issecured to and around thesleeve l9 whichsockets into the annularprojecting flange 29 of the housing.

Below the nozzle 2.41 I'provide a fuel pan 3!! into which a certainamount of fuel will drip when the jet 25 is opened and pressure has beenbuilt up in the tank I! by the pump 23. Associated with the pan as bestillustrated in the accompanying Figure 2 is a wick Si and a surroundingwick tube 32 the upper end of which projects into the pan and isnormally covered by the extinguisher 33.

The extinguisher is mounted for rotation on the stub shaft 34 (seeFigure 3) which is journalled in the pair of upstanding brackets 35secured to the pan 3%. Within the interior of the extinguisher I locatea flint-wheel 36, while against one wall of the extinguisher is mounteda small pinion 31, the extinguisher, flint-wheel and pinion rotating asa, unit.

In mesh with the pinion 3'! is a rack 38 connected to the push rod andfinger disc 39, the rod extendin through the projecting sleeve it on thepan, which sleeve contains a small coil spring 4!.

An upwardly spring pressed flint 42 bears against the fiint-wheel 36 andis contained within the receptacle &3 and from the foregoing, it willclearly be recognized that upon the impression of linear movementagainst the push rod in the direction of the arrow 53 (Figure 2), thepinions, flint-wheel and snuffer will be rotated in a clockwisedirection as indicated by the numeral 44 so that the upper end of thewick is uncovered, while, at the same time, a spark is thrown againstit.

The ignited wick sets fire to the fuel within the pan 3ii, which in turnignites the fuel proseeding from the jet 25 under pressure, and thus theblow torch is ignited. The contents of the pan are soon used up and aclean, hot flame is soon playing on the surfaces of the fire tubes I!and i2.

The alternative, electrically heated embodiment of my heater asillustrated in the accompanying Figures 5 and 6, may be located uponeither side of the bulkhead I although I have shown it connected uponthe cab side i. For this embodiment, I prefer to employ a verticalarrangement of tubes, although I do not wish to be restricted to avertical arrangement.

The vertical arrangement which I have shown in the accompanying Figure 5is similar to the horizontal arrangement of Figure 1 for which reason,the same numerology has been employed.

Intake and return water nipples 45 and 45 respectively project throughthe bulkhead to be connected via a hose or some other suitable connection to the water jacket of the associated engine.

Beneath the arrangement of tubes, is a heating chamber 51 containing anelectrical element or resistance 48. The heat from the resistance risesthrough the tubes H and i2, being allowed to escape through the exhaustport 49, and thus, it will be seen that I have provided a simple andeffective electrical embodiment which can readily be connected anddisconnected at the socket Ell by the operator of the automobile ortruck.

In conclusion, I would particularly point out that while my hereindescribed device obviously operates in a highly emcient manner tomaintain the temperature of water in an associated engine water jacket,the same is primarily designed, and conspicuously useful for heating thewater in subzero weather, and after an automobile, for instance, hasbeen exposed to such weather so that it is of the same temperature. Itwill be understood that in winter, the engine jacket will contain amixture of water and anti-freeze which, as is well known, does notfreeze solid, but only congeals into a semi-fluid mass at the lowesttemperatures likely to be encountered.

Since many modifications can be made in the invention herein describedand since the accompanying drawings have been prepared only toillustrate the relative arrangement and interaction of parts and, notwith regard to accuracy of dimensions for manufacturing purposes whichin view of this disclosure I consider to entail merely mechanical skilltogether with the skill of the mechanical draftsman, and since manyapparently widely different embodiments of this invention may be madewithin the scope of the accompanying claim without departing from thespirit and scope of the same it is intended that all matter contained inthe accompanying specification shall be interpreted as illustrative onlyand not in a limiting sense and I desire only such limitations placedthereon as justice dictates.
